As towman said, the 700r4 is adjusted at the TV (Throttle Valve) cable. Generally, changing the shift points to a little later will firm up the shift, but if you want an even firmer shift, then you can get a shift kit. Also on the 700r4, you can install the Corvette Servo for 1-2 shift, and that will just firm up the shift without changing the shift points.
On the Th350, you have both a detent cable that is equal to the TV cable of a 700r4, and a Vacuum Modulator, so you do have more room to play with on adjustment on the Th350. You can firm up the modulator to delay the shift a hair and firm up the shift, while you can also tighten up the detent cable that also does the kickdown, and change the shift points and really firm up the shift. Normally on a Th350, I tell people to set the vac modulator where you like the shift points at light and medium throttle, and then adjust the detent cable to where you like your full throttle shift points and down shift points.
Do keep in mind, a huge difference in the Th350 detent cable and the 700r4 TV cable, is that the 350 can operate just fine without the cable hooked up, let alone having the be adjusted correctly. Just that it won't kickdown and shifts may be early. On the 700r4, the TV cable MUST BE HOOKED UP, and needs to be adjusted within proper settings or you will fry the trans in very short order. Reason being, the 700r4 TV cable also regulates fluid pressure where the Th350 has its own seperate fluid pressure regulator within the vavle body. On the 700r4, if you don't have the TV cable hooked up to tell the transmission that you are going full or medium throttle, then the transmission doesn't know to increase the fluid pressure and hold the clutch packs tighter for the extra load, therefore, the trans thinks you are moving at light throttle with light fluid pressure so the clutches are now slipping and getting hot because they are not compressed tight enuogh. Hopefully that didn't confuse anyone. In short, Its OK to NOT hook up the cable on the Th350 although you probably won't like the shift points, but on a 700r4 the cable must be hooked up and adjusted properly or you'll fry the trans.
